First, I do not think you are crazy. I believe your symptoms are real; I am just not sure they are caused by an insect. I say this because one would not encounter black flies inside a home at this time of year. Also black flies are slow moving and big enough to see. I want to help you identify this insect that is biting you. You need to catch some and send them to me. If you can feel them on you , you might try collecting specimens using a lint roller. Then send the roller sheet to me and I will examine it under my microscope. Every time you feel something crawl on or bite you, roll the area with the lint roller. Use the same sheet over and over again, like a 100 times, until it is no longer sticky. Send me one and only one roller sheet. Wrap it with clear plastic wrap to keep it from sticking to the envelope. Mail it in a padded envelope or box to this address.
